NJU8713V-TE2

Overview

The NJU8713V-TE2 is a switching driver for Class D amplifiers manufactured by Nisshinbo Micro Devices Inc. It features separated power source terminals between input and output, along with BEEP and BPZ (Bipolar Zero) output circuits. The device converts 1-bit digital signals, such as PWM or PDM, into analog outputs via an external LC low-pass filter. Operating on CMOS technology, it supports an operating voltage range of 1.7V to 2.7V and a driving voltage from 1.7V to VDD. It is housed in an SSOP14 package.

Feature Summary

• Supports 2-channel 1-bit audio signal inputs
• Includes internal BPZ charger and beep function
• Enables standby mode with high impedance control

Applications

• Portable audio sets requiring high power efficiency
• Stereo OTL headphone amplifier configurations
• Single-channel BTL speaker amplifier setups

Procurement Notes

Verify the specific suffix TE2 against official documentation to confirm packaging details. Confirm that the component matches the SSOP14 outline and operates within the specified voltage limits. Ensure compatibility with the required master clock frequencies and input signal types before integration.

Selection Notes

Select this component for applications demanding high power efficiency through Class D operation. It is suitable for portable devices where low voltage operation is critical. Ensure the design accommodates the separate logic and driving power supplies for optimal performance.

Part Context

This part belongs to the NJU8713 series of audio ICs designed for low-voltage portable electronics. It integrates switching driver capabilities with specialized output control functions like BPZ and Beep, distinguishing it from standard linear audio drivers.

Replacement Considerations

FAQ

How does the NJU8713 handle output control?

Output states are selected via EN1 and EN2 terminals, allowing for Standby, Audio Signal Output, BPZ Output, or Beep Signal Output.

What is the purpose of the BPZ function?

The BPZ function charges the external AC coupling capacitor to establish the common point level for the analog signal output.
